Dots can appear in older sources, but never comma. Both I and Björn have a programming background, why using a decimal point is nothing strange, and may even come naturally. I seem to recall that the standards sort of change while I was in school, so that I was taught one separator one year and another separator the next year. (So the lapse did not really work as Mark assumed.) I also read the number as decimal at first, but I quickly realised that would be a completely pointless question to ask in a trivia game. > I do wonder about what rules apply to this kind of question.

There would be no point with the question if we would use any kind of aid. The key is to identify that the number is divisible by 9 and that the answer must end in 3. Then you need to do some math to find the range where the answer is hiding. The correct answer to Björn's assumed question is according to an SQL Server instance near me 3.8896015220071067, so his guess of 3.9 is correct to the precision he gave. -- Erland Sommarskog, Stockholm, esquel@sommarskog.se |

',' is thousand-separator in English ... Actually, I'm used to translate the Swedish decimal character ',' to the English '.' but here I did not even think of it. We use space ' ' as thousand-separator. (And when programming I use '_' as in 20_000_000, instead of 20000000, however the '_' does not *need* to be thousand-separator. That language is Ada) > misread the number.

And even if I would have read it correctly, I still would have fallen in he above traps, at least the sum of digits one. > For my part, I blame it on that it was too early in the morning and I > haven't had my cup of tea yet. I blame it on being at home, having a contractor tearing up our kitchen floor - fixing a water leak. He was NOT quiet. -- -- Björn |

Clever. I was a bit surprised by the question, but did not think too much of it. But now I see that it was more to it. -- -- Björn |

The easy thing I missed was the number is less than 15,625. -- Mark Brader | "Design an idiot-proof system, and the universe Toronto | will spontaneously evolve a higher grade of idiot msb@vex.net | that is able to circumvent it." |
